SURGEON-S OPERATING EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 246,599, dated September 6, 1881.

Application filed March 12, 1881.

at Decatur, in the county of Macon and State of Illinois, have invented a new and useful Improvement in Surgeons Operating Extension- Tables, ofwhich the following is a specification.

My invention relates to an improvement in surgeons operating extension-tables; and it consists, first, in the use of aframe or box having a folding top or leaves hinged together and pivoted on bars so as to bring the center ot'the fold in the center of the frame when theleaves are open; second, the use of extra supporting devices opening out of the ends of the frame to give an additional support to the leaves; and, third, the use of an adjustable end piece to one of the leaves; and the devices for operating the same. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a side elevation, showing top or leaves closed. Fig. 2 is a longitudinal vertical section on the line 00 00, Fig.3; and Fig.3 is an end view, showing the end support to the leaf.

A is a box-frame.

B B is the folding top, hinged at G O. The lower part, B, has pivoted to it, on the inside of the box-top, abar, D, which is also pivoted on the inside of theframe. The underleat', B, is provided with the end piece, E, which has two arms, 0 c, pivoted to the inside of the part B, so that it may be raised up to fill the opening in the end of each of the leaves B and B. When it is closed, as shown by dotted lines in Fig. 1, the incline pieces 0 c, Fig. 2, are secured to the inside of the frame A in such a manner as to raise the end piece, E, automatically when the leaves are closed. The object of this end piece being operative is to admit of a mattress being placed on the leaves without dividing it in two parts, as a division at that place is objectionable.

F F are parts, pivoted atf, which form panels at the ends of the frame A when closed, and when raised up serve as supports to the projecting ends of the leaves through the medium of the bar G, pivoted atg and having its lower end notched, so as to engage with the frame at a and retain it in position, as shown in Fig. 2.

I is a false bottom or cover to the drawers J (Model) J, on which the bars G G slide inside the frame when the parts F are closed, as represented in Fig. 1 by dotted lines.

H is a bottom to the main body of the frame or box A, and forms a receptacle for pillows and'other covering of the bed.

The device operates as follows, viz: The top is swung over to the left on the pivoted bars 1) D, the center of the cover or leaves coming in the center of the frame. The upper part, B, opens to the right. The parts or braces F F are opened out and upward, forming supports to the top B B. As the leaves are moved or swung to the right the end E, being removed from the support of the beveled pieces 6 6', drops, as shown. To close, theparts F F are replaced in the frame and the top closed together and moved to the right, the end E being raised up by contact with thebeveled pieces 6 c. This top may be used, without being made like a box, for a mattress by simply having the two parts B B a flat leaf and hinged together, and the lower part, B, provided with lugs similar to those shown atF in Fig. 2, to which the swinging bars D D may be pivoted.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The hinged top B B, provided with the pivoted arms DD, in combination with the frame A for opening, closing, and extending thetable, substantially as shown and described.

2. The parts F F, pivoted atff, and the pivoted and notched bar G, in combination with the hinged top BB and frame A, substantially as shown and described.

3. The end E, with the pivoted bars 0 e, in combination with the hinged top B B, frame A, and inclined pieces 0 c, substantially as WILLIAM J. OHENOWETH.
